PNG: The Definitive Guide: Source Code
|
|
|
|
Chapters 13, 14 and 15 of PNG: The Definitive Guide discuss three
|
|
cross-platform demo programs that show how to use the libpng reference
|
|
library: rpng, rpng2 and wpng. rpng and rpng2 are viewers; the first is a
|
|
very simple example that that shows how a standard file-viewer might use
|
|
libpng, while the second is designed to process streaming data and shows how
|
|
a web browser might be written. wpng is a simple command-line program that
|
|
reads binary PPM files (the ``raw'' RGB subset of NetPBM) and converts them
|
|
to PNG.
|
|
|
|
The source code for all three demo programs currently compiles only under
|
|
Unix and 32-bit Windows. It has been tested with gcc 2.7.2.3 under Linux and
|
|
Solaris and with Microsoft Visual C++ 5.0 under Windows 95. Brief
|
|
instructions for compiling the programs are included at the top of the
|
|
makefiles; makefile.unx is the Unix version, and makefile.w32 is (you
|
|
guessed it!) the version for 32-bit Windows. libpng and zlib are required.
